• Performing a fuzzy search may retrieve terms with similar spellings: (((((((("factores politicos") OR ("actores politicos"))) or ("efectos politicos"))) or ("valores politicos"))) or ("factores critico"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((((((("factores politicos") OR ("actores politicos"))) OR ("efectos politicos"))) OR ("valores politicos"))) OR ("factores critico")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((((\"factores politicos\") OR (\"actores politicos\"))) or (\"efectos politicos\"))) or (\"valores politicos\"))) or (\"factores critico\"))".
• Removing quotes may allow a broader search: (((((((( factores politicos ) OR ( actores politicos ))) or ( efectos politicos ))) or ( valores politicos ))) or ( factores critico )).
• Adding a wildcard symbol may retrieve word variants: (((((((("factores politicos") OR ("actores politicos"))) or ("efectos politicos"))) or ("valores politicos"))) or ("factores critico"))*.
